The #35011  2-speed transmission has a smoother gear change and
is less aggressive on the 2nd gear . 
We offer many different pinion and spur gear combinations 
which  can be used  for different  tracks.   

* Adjust the engine before adjusting the clutch shift timing.
  Adjust the engine as per engine instruction manual.

1. Once the engine adjustments  have been completed, proceed to the adjustment 
    of the clutch shift timing.
    (Using a 2mm allen wrench to adjust  the clutch shoes.)
    
    Note:
              Clockwise--------Shift timing will become slower.
              Counter Clockwise---Shift timing will become quicker.
 
2. Adjust the clutch shift timing for your  track conditions.
     As you tighten (Clockwise) the 3x15mm hex screw , the shift timing will become
     slower.
     As you loosen (Counter Clockwise ) the 3x15mm hex screw, the shift timing will 
     become quicker.

3. Set the shift  timing to the track conditions while the car is running.

* Use a 2mm and 2.5mm  allen wrench to 
  set the clutch shoes.

ADJUSTING THE SHIFT POINT

* Two steps to adjust  the shoes and  shift  timing.

6x6mm
Set Screw

6x6mm
Set Screw

1. Use a 2.5 mm allen wrench to 
adjust shoe assembly air gap.  
Tighten Set Screws, M6x6mm, to 
adjust the air gap between the 
shoe assembly and clutch bell 
wall.     Adjust both screws for an 
even amount of gap of about 
1mm.

 

2. Use a 2mm allen wrench to 

adjust the shift timing.  Turn, 
M3x15mm, screws IN until 
spring compresses, do not 
crush!  Back off screw 5 turns, 
this is a good place to start.

When adjusting shift timing, 
always turn each screw the 
same number turns.
